What crankset are you running right now?

If it is a square taper bottom bracket then you should be looking for an aftermarket crankset that is intended for a bottom bracket with ISO tapers.

The JIS taper looks very similar but has a different taper angle and although some have gotten them to work well they are not 100% interchangable and you can run into problems with the install and having them staying torqued to spec if you mix the two standards.
